The trench-arc-basin system of Southeast Asia is one of the most developed areas in the world, and there is a subduction-collision boundary which is still active nowadays between the Philippine Arc and the Sunda margin. Based on the previous research and the latest geological and geophysical data, the spatial distribution characteristics as well as the deformation characteristics of tectonic units on both sides of the tectonic boundary are systematically analyzed in this paper; we propose that the boundary begins from the east side of Taiwan coast plain in the northeastern South China Sea, then extends southward along the Manila Trench, through the thrust fault zone of Mindoro island, joints to the Negros Trench at the east edge of Sulu Sea, then the boundary goes through the thrust fault zone of Zamboanga and connects with the Cotabato Trench. According to the crust properties and interaction methods of the tectonic units on both sides of the boundary, the tectonic boundary can be divided into three types: arc-continent collision type, trench-subduction type and transitional type, and the different types of tectonic boundary have different significant characteristics in the geological and geophysical data. By the comparative analysis on the structural characteristics of the different sections of the boundary as well as the tectonic units on both sides of the boundary, we suggest that the crust properties on both sides of the boundary and the ancient tectonic position of the micro-continents of the west boundary are the main dynamic mechanism which leads to the significantly subsection characteristics of the tectonic boundary.
